JOHN M. DALY, OF PEORIA, ILLINOIS.

TONNAGE-RES|STANCE INDICATOR.

SPECIFICATION forming part of Letters Patent No. 715,200, dated December 2, 1902.

Application find December 30,1901. ser-:a1 No. 87,756. (Nomina To all wtont it may con/cern:

Be it known that I, JOHN M. DALY, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Tonnage-Resistance Indica tors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to an indicator for measuring the tonnage resistance in railway-trains, and especially does it refer to an improvement to indicators illustrated and described in applications prepared and filed on the 16th day of December, 1901, Serial No. 86,184, and the 30th day of September, 1901.

The object ot' the present invention is a sliding per-cent. chart carried in juxtaposition to the tonnage-chart and in the provision of means for fixing the chart in adjusted positions relative to the tonnage-chart.

The improvement may be more readily understood from the following description and the accompanying drawings, attached hereto, in which-V Figure 1 is afront elevation of my improved indicator. Fig. 2 is a plan view. Fig. 3 is a vertical cross-section. Fig. 4 is an end view, and Fig. 5 is a sectional view of certain details.

In the applications above referred to is disclosed an indicator in which is employed a revoluble per-cent. chart, one using paddles and the other a polygonal-shaped roll. In the present invention it is proposed to reduce the cost of the device and provide for an increased number of ratings over the devices referred to.

In the drawings, 1 refers to a case of suitable dimensions with a frame extension 2, comprising a back 3 and grooved sides 4. In the case is arranged a runway or trough 5, having beveled side portions 6 and 7. On Jthe beveled face 7 I arrange a tonnage-chart 8,V Which may be aiixed to the case or be impressed in the same.

9 indicates a board which is carried in the case and slidable inthe grooves 4 of the frame extension 2. Upon the outer face of the board, which is in full view, is arranged a per-y cent. chart 10, comprising a series of scales in successive order representing the hauling per cent. of engines, each` adjusted for use in conjunction with the tonnage-chart 8 substantially in the manner described in the applications referred to. The said board is arranged for perfect adjustment in a vertical manner relative to the tonnage-chart as to bring the successive scales of the chart l0 in juxtaposition to the said tonnage-chart for determining the per cent. of hauling of engines rated for specific tonnage on the chart. The arrangement of the grooves 4.- in the case enables the board to slide its length into the case, as may be seen in Fig. 8.

To provide for the board being adjusted and fixed in given positions to bring any one of the per-centscales adjacent to or opposite the tonnage-chart, a series of indentations or sockets ll are provided opposite each other in the frames 2, designed to be engaged by rods 12. There are shown two of these rods capable of being reciprocally carried in the board and are held outwardly, so that the outer ends of the rods normally engage coincident perforations 11 by means of springs 14, which bear around the rods and against a partition of the board at 15, through which the rods pass, and against collars 16 on said rods. On the inner matching ends of the rods are arranged linger-holds 17, adapted when the same are brought together to draw the rods 12 from the sockets 1l to permit the raising or lowering of the board 9. When released, the springs will force the rods'12 back into the grooves 4 in a manner to cause them to engage the next succeeding sockets 11 to retain the board in Aits adjusted positions.

In the drawings I have not endeavored to show a very extended per-cent. chart, but to convey the idea of what might beaccomplished in this improvement. The cost of production is moderate, and the same can be constructed in a comparatively Asimple n1an ner, the charts being printed upon a sheet of paper and pasted fiat on the board.

I do not Wish to be limited to the exact details shown nor to the manner-.of adjusting and retaining the board in adjusted positions, as details may be resorted to without affecting the invention herein. v

Having thus fully described my invention,

IOO

what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a device of the character described, a stationary tonnage-chart, a per-cent. chart carried adjacent to the tonnagechart and slidable relative thereto, and means for afixing the per-cent. chart in adjusted positions, as and for the purpose described.

2. In a device of the character described, a case, a longitudinal runway or trough therein, a tonnage-chart aiixed to the side of said runway, a slidable board or frame carried in the case at the rear of the runway and a percent. chart comprising a series of scales affixed thereto, and the means of adjusting said board, in the manner and for the purpose described.

3. An indicator of the class described, comprising a case with extended sides and back, said sides grooved in the manner shown and having perforations or depressions therein, a runway or trough in the case, a tonnage-chart affixed to the case, a slidable per-cent. chart movable in the grooved extensions of the case and means carried by the per-cent. chart arranged to be caused to engage said perforations or depressions in the grooved extensions for adjusting the height of the per-cent. chart relative to the tonnage-chart, substantially as described.

4. In a device of the character described, a case arranged with a tonnage-chart, extended sides of said case arranged with grooves, a series of perforations or depressions in the sides, a slidable per-cent. chart movable in said grooves, reciprocal rods carried by said per-cent. chart held under compression arranged to engage the successive perforations or depressions in the frame for adjusting the position of said scale relative to the tonnagechart, for the purpose described.

5. An indicator, comprising a fixed tonnage-chart, combined with a series of percent. charts attached to or impressed on a member capable of reciprocation, the said per-cent. charts indicating hauling per cent. of engines, and increasing in length from top to bottom of chart, and means for adjusting said member to bring each of said charts in juxtaposition to the fixed chart, as and for the purposes set forth.

G. In a device of the character described, the combination of a case having reduced side extensions and an extended back, and the sides having vertical grooved portions, a tonnage-chart suitably arranged in the case, a board slidably arranged in the aforesaid grooves and bearing on one face suitable scales coacting with the tonnage-chart, and means carried by said board iexibly held in engagement with means of the case and the same adjusted whereby the board may be raised and lowered, Substantially for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

f JOHN M. DALY.
